INTRODUCTION
T-Prime 130-1 is an epoxy tooling system for manufacturing glass or carbon moulds from liquid infusion processes.
T-Prime 130-1 is compatible with Gurit’s range of 130°C tooling gelcoat, laminating and repair systems.
T-Prime 130-1 is a low shrinkage ambient curing system, which provides a simple way to produce high accuracy
moulds. Designed for infusion and cure at ambient temperatures, it should then be mid-cured at 40°C (104°F) for 4
hours to guarantee the strength needed for demoulding. It can then be postcured off the plug to give a material that
is thermally stable to 130°C (266°F). Exceeding this temperature will cause a rapid loss in stiffness and a safety
margin is required for the maximum tool operating temperature to prevent distortion or tool damage.
T-Prime 130-1 is a further improvement on T-Prime 130 giving improved storage stability and an extended pot-life.

* Pot life in larger volumes can be reduced. Material approaching its pot life is typically 40-50°C (104 – 122°F) in the centre of the pot and it will then thicken as it cools
in the laminate and feed pipes. This material will have already seen higher temperature will reach a higher viscosity more quickly than the thin film data at a given

Large volumes of T-Prime 130-1 left in bulk > 50mm deep can exotherm strongly and the excess will need to be dispensed into a
shallower vessel. Ideally this should be less than 30mm deep or the pot placed into water to cool.

APPLICATION NOTES
n A good level of understanding of the infusion process is
required to achieve a high quality mould. Contact SP-High
Modulus for further advice or refer to SP-High Modulus process
notes for further information.
n Any deviation from the prescribed mix ratio may degrade the
thermal capability and physical properties of the material
n Recommended workshop temperature is between 18°C and
25°C (64°F and 77°F)
n If “drill” style mixing is used, this must be on the lowest
setting to reduce the air introduced. Particular attention is
needed to mix the sides and bottom of the container
n Allowing the mixed resin to stand for 5-10 minutes before
use in order to allow air to dissipate to improve the final
laminate quality.
n For large components pre-weigh and dispense into labelled
or coloured pots rather than pre-mix all the material to extend
pot life for large infusions. This also avoids potential exotherm
problems with large quantities of unused mixed system.
n If large quantities are left in feed buckets and vacuum pots
at the end of the infusion it is recommended to transfer some
of the bulk material into a shallow vessel, with a large surface
area, to dissipate heat. It is recommended to always keep the
bottom of feed pipes covered in resin to avoid the risk of air
inclusion even after the feed pipes are closed / clamped.
n Depending on the infusion design it can take a large amount
of time to infuse the final 10% of a part as the flow rate slows
with distance from the final feed pipe. This is a critical time to
monitor the resin pot life and change to new resin if required.
Material close to the pot life can build in viscosity and block the
feed pipes. If the infusion is running slowly it is recommended
to allow the resin levels to lower in the feed pot and aim to
supply new resin every 2.5 hours at 20°C and 1 to 1.5 hours at
25°C if there looks like there will be a problem with filling the
final laminate.
4
n If emptying a receiving bucket inside a vacuum pot
remember to allow time for the vacuum to fully build back up
inside the pot before opening the control valves to the part
otherwise any air inside the vacuum pot may be pulled back into
the part.
n If using T-Gel 130-1 Slow allow at least 24 hours at 20°C
(68°F) before applying vacuum to begin the infusion to ensure
sufficient stiffness of T-Gel 130-1. Infusing too soon can lift the
gelcoat and cause sink marks.
CURED PROPERTIES
AMBIENT CURE
The mechanical strength after 24 hours at 20°C (68°F) is still
low and a mid cure is needed to de-mould.
If more than one infusion stage is used allow at least 2 days
at 20°C (68°F), or cure elevated temperature, before removing
peel ply and other infusion consumables. This is to remove the
risk of delamination and subsequent blisters from lifting the
part cured laminate.
If peel ply is removed before a full cure the part cured shards
of resin created can contain a significant amount of un-reacted
epoxy. Un-reacted epoxy dust is a particular skin irritant and
the appropriate personal protective equipment (PPE) should be
used.
MID CURE
A mid cure of at least 4 hours at 40°C (104°F) is
recommended before de-moulding to maximise gelcoat
adhesion and build sufficient resin strength for demould.
Ramp rate is not critical at this stage.
PDS-TPrime130-1-4-0515
POST CURE
To achieve full postcure ramp at 0.2°C /min to 120°C (8.5 hours) and dwell for 2 hours (0.36°F /min to 248°F). Faster postcure risks
thermal softening of the tool. Contact SP for advice when in doubt.

A general 10 to 15% waste value is then recommended for purchase estimation. Additional resin is also required for infusion
consumables. Resin waste in feed meshes and pipework depends on the component geometry and infusion design. As approx
guide resin allow;
n Small Infusion (Up to 2m2)
Approx 2 Kg/m2 (Generally have a higher % waste)
n Large Infusion (20m2 and above) Approx 1 Kg/m2
For the first components, and when new to infusion, allow extra resin for feed pots.

HEALTH AND SAFETY
The T-Prime 130-1 system has been designed for use in closed
mould processes. Users should ensure that some elevated
temperature cure is applied to the component before trying to
machine it. In a component made from T-Prime 130-1, which has
seen no heat, there will only be a partial cure. Therefore the
sanding dust will be more irritating than dust from a laminate
cured at elevated temperature, in which there will be more
thorough cross linking. Particular care should also be taken
when removing peel plies from part cured material as this can
also product a dust like particle, and an elevated cure or
personal protective equipment is recommended.
5. If the skin becomes contaminated, then the area must be
immediately cleansed. The use of resin-removing cleansers
is recommended. To finish, wash with soap and warm
water. The use of solvents on the skin to remove resins etc
must be avoided.
Washing should be part of routine practice:
n before eating or drinking
n before smoking
n before using the lavatory
n after finishing work
The following points must be considered:
1. Skin contact must be avoided by wearing protective gloves.
Gurit recommends the use of disposable nitrile gloves for
most applications. The use of barrier creams is not
recommended, but to preserve skin condition a
moisturising cream should be used after washing.
2. Overalls or other protective clothing should be worn when
mixing, laminating or sanding. Contaminated work clothes
should be thoroughly cleaned before re-use.
3. Eye protection should be worn if there is a risk of resin,
hardener, solvent or dust entering the eyes. If this occurs
flush the eye with water for 15 minutes, holding the eyelid
open, and seek medical attention.
4. Ensure adequate ventilation in work areas. Respiratory
protection should be worn if there is insufficient ventilation.
Solvent vapours should not be inhaled as they can cause
dizziness, headaches, loss of consciousness and can have
long term health effects.
PDS-TPrime130-1-4-0515
6. The inhalation of sanding dust should be avoided and if it
settles on the skin then it should be washed off. After more
extensive sanding operations a shower/bath and hair wash
is advised.
Gurit produces a separate full Safety Data Sheet for all
hazardous products. Please ensure that you have the correct
SDS to hand for the materials you are using before
commencing work. A more detailed guide for the safe use of
Gurit resin systems is also available from Gurit, and can be

TRANSPORT & STORAGE
The resin and hardener should be kept in securely closed containers during transport and
storage. Any accidental spillage should be soaked up with sand, sawdust, cotton waste or any
other absorbent material. The area should then be washed clean (see appropriate Safety Data
Sheet).
Adequate long term storage conditions will result in a shelf life of 12 months for both the resin
and hardener. Storage should be in a warm dry place out of direct sunlight and protected from
frost. The temperature should be between 10°C and 25°C. Containers should be firmly
closed. Hardeners, in particular, will suffer serious degradation if left exposed to air. The
materials should be stirred before use.
